There is a monograph on dreams, Duke Zhou. However, the interpretation of dreams in Duke Zhou is not from a scientific point of view. We prefer to think that dreams neither represent good luck or bad luck, nor predict the future. This view originated from Freud's Interpretation of Dreams.
When people sleep, brain cells also enter a state of relaxation and rest, but some brain cells are not completely rested, and weak stimulation will cause their activities, thus producing dreams.
For example, there is something that makes you particularly excited during the day, and you are still thinking about it before going to bed. When other nerve cells in the brain are at rest and these nerve cells are still excited, you will have a dream with similar content, which is called "thinking day and night".
Psychologist Freud believes that dreams are the satisfaction of subconscious desires, and people can effectively suppress the subconscious when they are awake, so that those desires that violate moral customs cannot do whatever they want. However, when people fall asleep or relax, some desires will avoid the inspection of the subconscious, secretly emerge from the conscious level, and show themselves in various images. This is the formation of dreams.
Dreams are substitutes for human desires and the main way to release depression. No matter in which country, people have the highest recognition of Freud's theory and think that dreams have deep meanings.
First of all, you should know that dreaming does not mean good luck or foretell the future, so don't give yourself bad psychological hints, which is more harmful than anything else. If you can't explain the content of a specific dream, there is no need to force it. In short, you have some psychological pressure in this respect, and you should find out what it is. When you wake up, it's all over.
